JOHN HEDDON, or ELKHART, INDIANA.

PHOTOGRAPHIC PRINTING-FRAME.

Specification forming part Of Letters Patent No. 70,564, dated November5, 1867.

To all whom fit may concern:

Be it known that I, JOHN HEDDON, of Elkhart, in the county of Elkhartand State of Indiana, have invented a new and Improved PhotographicPrinting-Frame for making an indefinite number of photographs of thesame or of different persons or subjects upon one piece of paper orother photographic material; and I do hereby declare th at the followingis a full and exact description thereof, reference being' had to theaccompanying drawings, and to the letters and figures marked thereon.

The nature of my invention consists of a frame, a perforated grouping-board, and a vignetting arrangement.

Figure l is a perspective view of the frame, having a broad flange ateach end, Figs. 2 and 3, to exclude the light from the sensitized paperinv printing when the grouping board, which is an inch or more shorterthan the inside of the frame, is moved to either extreme end. Y

The grouping-board, Fig. 4, may be made of wood or card-board Or othermateria1,restin g upon a plate of glass. It is perforated with holesarranged in the form of the group to be printed, and is made shorterthan the frame to facilitate the arrangement of the various negativesrequired for printing, and is equivalent tO a movable back. (This framewill make an endless variety Of work by simply changing thegrouping-board.) The set-screw, Fig. 5, keeps it in place.

The back, Fig. 6, is composed of live pieces, a, b, e, d, and e, but maybe increased or diminished in number to suit different sized frames, andalso to make different sizes and kinds of groups in one and the sameframe. Each piece is detached from all the rest, and can be opened whilethe others are closed. They may be bolted or fastened together, thusmaking one compact back, or any fastening may be removed and any jointbe Opened to see the progress of the printing, each piece having aspring-hinge and clasp. This frame back is so arranged that the printingmay be viewed with equal facility at either end of the frame.

The vignetting, Fig, 7, is composed of two sliding pieces, e and f,running at right angles, which covers the front of the frame, the piecef having an opening nearly across it, in which runs the slide e, havinga hole in the center for printing through, and using a tube tOeffectually exclude the light from other parts Of the sensitive paperthan the one being printed. By this double motion one can readily followthe form underneath in the grouping-board, making any kind of a print orarrangement of grouping desired.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The hinged back, of five pieces, more or less, so constructed thatany two or more may be fastened together, or an opening be effected ateither of the joints, thus admitting the cx aminaticn of the printingfrom either end of the frame.

2. Also, the broad flanges, in connection with the adjustable groupingboard, which movable perforated board, or any other material answeringthe same purpose, I also claim, this being equivalent to the movable orsliding frame for carrying the back up or down.

3. I claim the adjustable and sliding back 5 also, the vignettingarrangement for excluding the light from the sensitive paper, by the useof the two pieces Of board Or other material, -with a tube forconduct-ing the rays of light to the negative.

4. I claim this invention separately and as a whole, in combination Onewith the other, substantially as set forth above.

JOHN HEDDON.
